Kulebiaka Flaky Salmon Loaf

PASTRY
For the pastry combine the flour, chilled butter, the vegetable fat cut into cubes and the salt in the work bowl.
Process for some 10 seconds until it has the texture of breadcrumbs.
Add the chilled water all at once and process only for a few seconds until the pastry starts to form a ball.
Remove the pastry on to a sheet of aluminium foil, press into a ball and refrigerate for 1-2 hours or until firm
